         5 . The file presenting method for a smart terminal of  claim 4 , wherein, after generating the thumbnail of the file in accordance with the loading information of the file and storing the generated thumbnail to the second level cache of the smart terminal, the method comprises:
 storing the generated thumbnail to the first level cache of the smart terminal in accordance with a Least Recently Used (LRU) algorithm.   
     
     
         6 . The file presenting method for a smart terminal of  claim 1 , wherein the method further comprises:
 receiving a command to present a file management page;   emptying the loading queue.   
     
     
         7 . The file presenting method for a smart terminal of  claim 1 , wherein the method further comprises:
 when the user interface thread determines that it is not to present the thumbnail of the file according to the type of the file, presenting a preset default icon.   
     
     
         8 . The file presenting method for a smart terminal of  claim 1 , wherein the method further comprises:
 before presenting the thumbnail of the file as the icon of the file, presenting a preset default icon as the icon of the file.   
     
     
         9 . A file presenting apparatus for a smart terminal, the apparatus comprising a loading queue setting unit, a thumbnail acquiring unit, and a thumbnail presenting unit, wherein:
 the loading queue setting unit is configured to enable a user interface thread to determine whether it is to present a thumbnail of a file according to a type of the file, and set loading information of the file in a loading queue if it is;   the thumbnail acquiring unit is configured to enable a loading thread to acquire the loading information of the file from the loading queue, determine whether a cache of the smart terminal stores the thumbnail of the file, generate the thumbnail of the file in accordance with the loading information of the file and store the generated thumbnail to the cache of the smart terminal if the cache of the smart terminal does not, and acquire the thumbnail of the file from the cache of the smart terminal if the cache of the smart terminal does; and   the thumbnail presenting unit is configured to present the thumbnail of the file as an icon of the file.
